EXTENSIBLE CURTAIN-ROLLER.

Specification of Letters Patent.

Iatentml June 9, 1914.

Application filed January 29, 1912. Serial No. (574,002.

To all whom it may concern:

Be it known that I, FRANCIS N. Kozmnt, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Extensible Curtain-Rollers, of which the following is a specification. 7

My invention relates to rollers for window curtains, awnings, and the like, and more particularly to curtain --rollers which are capable of being adjusted longitudinally as occasion may require or render desirable.

The principal objects of the present invention are to provide an extensible curtain roller which will be strong. anddurable in construction, which will be readily adjustable within comparatively .wide limits, and which, when once adjusted to a desired length, may be further extended or the main parts entirely separated from each other without impairing the possibility of immediately putting the roller into its first adjustment. without any further measurements or other efl'ort usually required where the relationship of parts has been destroyed.

These and other advantages obtained through my invention will be morereadily understood by referenceto the accompanying drawings, forming a part of this specification, in which Figure 1 is a broken view showing in elevation a preferred embodiment of the improved extensible .curtain roller herein de scribed, Fig. 2 is an enlarged vertical longitudinal section of the middle portion of the-roller taken on the line 2-.-2 of Fig. 3, Fig.3 is a sectional view on the line 33 of Fig. 1, at right angles thereto, and Fig. 4 is a sectional view similar to that of Fig. 3, and illustrates a modified form of the stop or adjusting means.

The roller proper comprises the main section 10 and the end section 11,. the latter having a tubular portion 11 rigidly secured Within the same and adapted to telescope into section 10. The tubular portion 11' is of such length that when. the roller is extended to the greatest limit called for by the use thereof there will still be sufficient of the portion 11 within the section 10 to provide rigidity and strength. This portion 11 is provided with a slot 12, the approximate shape and extent of which is substantially shown by dotted lines in Fig. 1. This slot 12 not only constitutes away for the travel of the adjusting and clamping screw, hereinafter to be described, but has an important function also in providing resiliency and. spring in said portion whereby it is maintained in suitable frictional contact with the inner surface of the section 10.

As well indicated in Figs. 3 and 4 the ex tension 11', is provided with a semicircular longitudinal indentation 13 adapted to accommodate the rib-like formation 14 in the section 10, thus locking the two sections 10 and 11 against rotation relative to each other. The formation 14:, in its interior aspect, constitutes an undercut groove or longitudinal recess which extends not only throughout the length of section 10, but also that of section 11, as well as that in the construction illustrated, of the stop or adjustment member 15, hereinafter to be described, this groove being formed to receive the curtain and to hold the same upon the roller, as is well understood, this groove method of attaching the curtain being old.

The stop 15, in its preferred form, comprises a band, preferably of tin, formed to fit tightly andv yet slidably upon the tubular portion 11, and is held fixedly in any desired position upon such portion by means of the wood screw 17 passing through an aperture in the band 15, through the slot; 12 and into the block 16. The tightening action of the screw draws the Wooden block and the band together, thereby tightly clamping these parts upon the edges of the extension 11. adjacent to the slot '12. By loosening the screw 17 slightly it is evident that the stop 15 may be moved in either direction upon. the telescopic portion 11. lVhile it has been found convenient to provide a curtain retaining groove 14 in this band in alinement with the same groove in the sections 10 and 11, this is not an essenexactly that required by the particular occaalso gives rigidity and strength to the portion 11. It is plain that the two sections may now be entirely separated for purposes ot-repair or otherwise, and may be readily put together again 1n exactly the desired condition without further measurements or thought as to the'ad ustment. This feature of the invention is of great importance and will be readily appreciated by those skilled in the art.

Rollers of this type are usually provided with spring mechanism for winding the curtain upon-the roller after the same has been unwound therefrom; but as this mechanism is well known and constitutes no part of the present invention it is not illustrated or described. The roller is supported in operative position by brackets (not shown) iirengage ment with the end members 20 and 21 in the usual manner.

such as tin.

The invention is not, limited to the details of construction or arrangement of parts hereinabove described or as illustrated in the drawings as it will be apparent to those skilled in the art that many changes may be made therein without departing from the spirit or scope of the invention.

I claim 1. In an extensible curtain roller,-the combination of apmain section, an end section adapted to telescope therein, and a stop ad'- justable on said end section whereby the inward telescopic movement thereof is limited, substantially as described.

2. In an extensible curtain roller, the combination of a roller proper comprising main section and an end section, said. sections being formed totelescope together, and means adjustable on one of said sections for limiting the shortening telescopic movement of said sections, without preventing the lengthening telescopic movement thereof, substantially as described.

In the construction illus'-" trated' the roller is made of light sheet metal,

7 3. In an extensible curtain roller, the combination of a roller proper comprising a main section and an end'section, said sections being formed to telescope adjustably together, and means. adjustable on one of said sections for limiting the, shortening tele- =scopic movement of said sections without preventing the lengthening telescopic movement thereof, substantially as described.

4'. In an extensible curtain roller, the combination of a roller proper comprising a main section and a slotted end section formed to telescope adj ustably into the main section,-means adjustable on said end section for limiting thetelescopic movement thereof into said main section, and a' clamp for said adjustable means comprising a member in said end section, and a screw extended through the slot of said end" section, substa'ntially as described;

5; an extensible curtain roller, aroller proper comprising a pluralityof telescopic sections, one of said sections being slotted, and means adjustable in said slot for preventing inward telescopic movement of said slotted section while permittingoutward telescopic movement thereof, substantially as? described; 6. In an extensible curtain roller, the combination oftelesc'opically arrai'ige'd sections,

a band arran ed about the inner section andv having an outer'diameter substantially equal tothat of the outer section, and means to adju'stably POSitlOii the band on theinner section to limit the inward telescopic movemeut of the sections, substantially as" de-' scr bed; 1 7. In an extensible curtainroller, theeom bination of telescopically arranged sections of substantially the same general diameter,

the inner section having its end portion re duced tofit within the outer section, a band 1. V K Y v 4 arranged about the reduced port on of the inner section and having an outer diameter substantially equal to that of the general" diameter of the sections, and means toadjus'ta'bly position the band-longitudinally onthe reduced portion of the inner section to limit the shortening telescopic movement of the sections, substantially as described;
